Data and Appendix for Original Research Paper "Emotions and Prior Outcomes Shape Risk Propensity and the Dynamics of Decision Making in BART"

Decisions under uncertainty often emerge from the interaction of affective and cognitive processes. Using the Balloon Analogue Risk Task (BART), this study investigated how incidental emotions (happiness, sadness, anger, fear) and prior outcomes shape risk-taking. Sixty-six participants performed the BART while exposed to images evoking emotions or neutral affect. Results revealed that exposure to anger- and fear-evoking stimuli significantly reduced risk-taking, suggesting these highly arousing negative emotions may disrupt engagement and promote avoidance behaviors. Additionally, participants demonstrated heightened risk propensity and prolonged decision times following a successful trial, indicating a cognitive reframing of subsequent decisions after gains. These findings highlight how emotional and contextual cues jointly shape risky behavior in uncertain environments, advancing our understanding of affect-cognition interplay in decision processes.<br>

不确定性情境下的决策往往源于情感与认知过程的交互作用。本研究采用气球模拟风险任务（Balloon Analogue Risk Task, BART），探究了偶发情绪（快乐、悲伤、愤怒、恐惧）与既往结果如何影响风险决策行为。66名参与者在观看诱发特定情绪或中性情绪的图片时完成了BART任务。研究结果显示，接触愤怒与恐惧诱发刺激的参与者，其风险决策行为显著降低，表明这类高唤醒负面情绪可能会破坏任务投入度并促发回避行为。此外，成功完成一轮试次后，参与者表现出更高的风险倾向与更长的决策时长，这表明个体在获得收益后会对后续决策进行认知重构。本研究结果揭示了情绪与情境线索如何共同塑造不确定性情境下的风险行为，深化了我们对决策过程中情感-认知交互作用的理解。
